Shetland sheep are fierce survivors, known to be easy to breed since they don’t ask for much. It makes sense when you consider their native habitat--the frigid, windswept Shetland Isles, an archipelago due west of Norway which is the northernmost part of Scotland. Shetland wool, which Scottish fishermen have relied on for centuries, has a similar character to the animals it comes from. Lightweight and warm, it doesn’t ask much of whoever wears it, but keeps him or her insulated from the cold with stoic composure. Visually, however, it’s far from sedate--heathered yarns imbue Shetland’s gauzy surface with vivid, multi-dimensional color that gets more complex the closer you look.
